Kantong Semar (Nepenthes) tergolong tumbuhan karnivora yang dapat di temukan di beberapa hutan di Indonesia dengan beragam bentuk.Keunikan tumbuhan ini berasal dari kantong yang di modifiaksi oleh daun sebagai mekanisme pertahanan diri untuk mendapatkan makanan. Kawasan hutan Sultan Daulat Kota Subulusaalam Provinsi Aceh tepatnya di  perbukitan yang di tumbuhi paku resam yang menjadi salah satu habitat dari tumbuhan Kantong Semar (Nepenthes). Penelitian ini penting di lakukan karena belum adanya data mengenai tumbuhan Kantong Semar (Nepenthes) di daerah tersebut.Penelitian ini di lakukan pada bulan Januari 2021 yang bertujuan untuk mengidentifikasi tumbuahn Kantong Semar (Nepenthes) serta pola penyebarannya. Penelitian ini mengguanakan metode survey eksploratif  yaitu dengan cara jelajah langsung dan penentuan jalur pengamatan mengguanakan jalut transek senanyak 5 transek, tiap transek di buat 5 plot, luas plot pengamatan 20 x 20 m yang ditempatkan secara purposif sampling.  Hasil penelitian di temukan 4 spesies tumbuhan Kantong Semar (Nepenthes), yaitu: Nepenthes ampullaria 51 individu, Nepenthes gracilis 143 individu, Nepenthes mirabilis 171 individu, dan Nepenthes reinwardtiana 98 indidu. Pola penyebaran tumbuhan Kantong Semar (Nepenthes) di kawasan hutan Sultan Daulat yang di uji dengan Standart  Indeks Morisita Ip > 0 menunjukkan pola penyebaran tergolong mengelompok (Clumped).

Indeks keanekaragaman (H’) sebesar 0,36 dan tergolong rendah. Karakteristik fenotif jumlah daun steril berkisar 2-37 helai, daun fertil berkisar 1-12 helai, panjang daun berkisar 9,5-37,2 cm, lebar daun berkisar 1,7-8,2 cm dan tebal daun berkisar 2,1-3,6 mm. Panjang kantong berkisar 3,4-22,2 cm dan diameter kantong berkisar 1,6-4,4 cm. Bentuk silinder (gracilis), tempayan (ampullaria), terompet (rafflesiana kantong atas), bulat telur (rafflesiana kantong bawah). Variasi corak kantong berupa bintik-bintik merah, sayap dan renda bervariasi, kantong atas tidak bersayap, yang bersayap umumnya kantong bawah dan ber-renda, tutup kantong terdiri atas bentuk proporsional dan tak proporsional.

Kantong semar (Nepenthes spp.) merupakan tumbuhan karnivora yang hidup didaerah tropis salah satunya di Cagar Alam Lembah Harau, tingginya tingkatan eksplorasi dan penjualan nepenthes sebagai tanaman hias diperkirakan dapat menurunkan jumlah spesies nepenthes, saat ini kantong semar (Nepenthes spp) termasuk kedalam CITES (Convension On International Trade Of Endangered Spesies) dalam Apendiks I dan II yang tergolong hampir punah dan langka.Penelitian ini adalah penelitian deskriptif dengan menggunakan metode survey. Penelitian dilakukan pada mulai bulan Oktober - November 2014 di Kawasan Cagar Alam Lembah Harau Kabupaten Lima Puluh Kota Sumatera Barat. Teknik pengumpulan data dilakukan dengan observasi langsung dilapangan, serta mengidentifikasi spesies yang didapatkan di Laboratorium Biologi STKIP Abdi Pendidikan Payakumbuh.Berdasarkan hasil penelitiandidapatkan 4 spesies kantong semar (Nepenthes spp ) yaitu Nepenthes Albomarginata, Nepenthes ampullaria Jack, Nepenthes eustachya Miq, Nepenthes gracilis Korth dikawasan Cagar Alam Lembah Harau. Spesies kantong semar yang ditemukan di lokasi penelitian pada umumnya tumbuh di tanah atau terrestrial dengan batang memanjat (scandes).

This study is aimed to recognise the morphological characteristics of Nepenthes mirabilis and Nepenthes gracilis in peat swamp area including stem, leaf, tendril, pitcher, flower, fruit, and seed.  This study has been conducted in January  until April 2018, located in Petaling Village Tulung Selapan Sub-District, Ogan Komering Ilir, South Sumatera. This study uses an exploratory method and the the observation sample using the method of random plot is chosen by purposive sampling. Parameters observed morphological characteristics of Nepenthes include stems, leaves, tendrils, pitcher, flower, adn fruit, as well as measurement of environmental factors. Based on the study, the researcher obtained two types of Nepenthes which are Nepenthes mirabilis and Nepenthes gracilis in  peat swamp area of Petaling Village Tulung Selapan Sub-District, Ogan Komering Ilir. Nepenthes mirabilis has a teres stem, leaves that in the form of oblong to lanceolate, has a petiolate, the edge of the leaves is flat covered by smoothy hair, thick peristome in size of 0,4-0,5 cm. Meanwhile stem Nepenthes gracilis has triangular stem, leaves in formed of lanceolate, sessile, flat edge of leaves, thin peristome in size of 0,1-0,2 cm. The pitcher shape of Nepenthes mirabilis and Nepenthes gracilis are cylindrical, infundibulate, and waist. The flower of Nepenthes mirabilis and Nepenthes gracilis are compound in type of  raceme inflorescences. The fruit is formed as capsula, has four lobed, and contains numerous seeds. The seed is spindle-like and white colored.

Nepenthes Gracilis

We review the biomechanics, functional morphology, and physiology of motile traps. The movements of snap traps in Aldrovanda and Dionaea, motile adhesive traps in Drosera and Pinguicula, and suction traps in Utricularia are driven by active water displacement processes leading to reversible turgor changes of motor cells, irreversible growth, or mechanical pre-stressing of tissues. In some cases, the motion is amplified by the release of elastic energy stored in these tissues. The only known case of a passive motile trapping movement is the ‘springboard’ trapping mechanism of Nepenthes gracilis, in which a rapid vibration of the pitcher lid is actuated by the impact force of raindrops. Open research questions are summarized and future studies are suggested.

Nepenthes Gracilis

Kalampangan peat swamp forests in Central Kalimantan is home for Nepenthes spp. However, the number of Nephentes has been reduced due to massive forest fires and land conversion for housing and agricultural purposes. Nepenthes is a unique plant with ability to prey insects, hence often referred to as 'insectivorous plant'. This study investigates the distribution of Nepenthes spp. in Kalampangan forest through ground check and qualitative descriptive approach. A total of six observation plots measuring of 2m x 2m were used purposively. The results show there are four Nepenthes species found, namely Nepenthes gracilis, Nepenthes mirabilis, Nepenthes gracilis cortis, and Nepenthes ampularia. The highest Morisita index is 1.06 while the lowest one is 1.01.
